Abstract: 1508631 Closing containers IN DA TE AG 19 Jan 1976 [20 Jan 1975] 2402/75 Heading B8T A re-usable container, formed preferably from stainless steel, laquered tin-plate or aluminium, has a mouth ring 5, preferably formed of natural or synthetic rubber or stainless steel, bonded to the end 6 of its wall 1 by adhesive or welding as appropriate. The mouth ring 5 is thicker than the wall 1 and has its internal surface shaped to receive and lock in position upstanding peripheral flange 10 of a tin-plate closure 11. In the embodiment of Fig. 3 the flange 10 is received against a face 9 which slopes outwardly, e.g. at an angle of 10 degrees to the vertical and locked in position by a barb 12. An upstanding annular shoulder 13 extends into a recess 17 in the closure 11 against a resilient sealing member 19. The chamfered surface 7 bears against a matching surface on a ring of sealing material of a filling apparatus (Fig. 4, not shown). The container is opened by pressing downwardly on the centre of the closure by means of a plunger thereby causing the flange 10 to be released from the barb 12. In the embodiment of Fig. 5 the mouth ring 5 is rolled from a strip of the same material as the container. In the embodiment of Fig. 6 a groove 28 constitutes a seating for an 0-ring seal 29 against which the flat bottom of the closure 11 is pressed into engagement. The container and mouth ring are constructed to facilitate stacking of empty containers one within another. Instead of an integral base 2, the lower end of the container may have a second mouth ring 5 and closure 11. When the container is empty the second closure is removed, thereby facilitating cleaning of the container.

Abstract: 1,135,889. Filter networks. HAZELTINE CORP. 25 Sept., 1967 [5 Oct., 1966], No. 2713/68. Divided out of 1,135,888. Heading H3U. Two circuits operative over different frequency bands are connected by a resistance device including a body of lossy dielectric material and providing a high resistance in the higher band and a low resistance in the lower band. As shown, the two circuits are the UHF tank circuit 13, 14 and the VHF tank circuit 15, 17 of the local oscillator of a television receiver and are tunable by a slider movable along first one and then the other coil. The device 18 has a low resistance in the VHF band and allows the VHF circuit to be effective but at UHF the VHF circuit is ineffective because of the high resistance of the device 18. The feedback through capacitor 20 is augmented at VHF by feedback through a circuit 21 which in the UHF acts like a choke and provides no coupling. The device 18 also serves to damp spurious resonances in the VHF circuit when the oscillator is operating at UHF.

Abstract: Quinoline aldehydes are prepared by a process wherein a methyl quinoline together with up to four times the theoretical quantity of an oxygen-containing gas (the theoretical quantity of oxygen being based on one molecule of oxygen per methyl group in the methyl quinoline) and water vapour as an inert diluent, are passed in the vapour phase at a temperature above 250 DEG  C. over an oxidation catalyst comprising at least one oxide of a metal of sub-group a of the 5th, 6th or 7th groups of the periodic system in the absence of iron oxide or copper oxide.  The invention also comprises an addition compound consisting of 1 mol. of quinoline-4-aldehyde, 1 mol. of lepidine and 2 mols. of water of crystallization having a melting-point of 60-62 DEG  C.  The reaction chamber containing the catalyst is conveniently in the form of a tube constructed of aluminium, nickel, a precious metal or a ceramic material.  Nitrogen may also be used as a further diluent in the reaction mixture.  The crystalline intermediate product referred to above is obtained, in the oxidation of lepidine (4-methylquinoline), from the condensed reaction mixture after it leaves the reaction zone.  In examples: (1) quinaldine, air and water vapour are passed at 410 DEG  C. over a 10 per cent molybdenum trioxide on silica gel catalyst, the reaction product is condensed, cooled, extracted with chloroform, the chloroform extract of aldehyde treated with sodium bisulphite solution, the quinoline-2-aldehyde being liberated from the bisulphite compound by treatment with saturated sodium carbonate solution (the quinoline-2-aldehyde may be dimerized to 2-quinaldoin by heating or by the addition of potassium cyanide solution); (2) as in (1) but oxidizing lepidine, the solid intermediate described above is obtained in the condensate, the free aldehyde being liberated therefrom by the action of sodium bisulphite solution.

A magnetic switch driven by a meter to provide impulses at each revolution thereof has a permanent magnet 24 on an eccentrically weighted arm 12 freely rotatable on a shaft 8 and driven by a projecting stud 18 on a freely rotatable weight 10 on the shaft 8. The weight 10 is driven by a stud 16 on a collar 14 secured to the shaft 8 which is coupled to the meter. The studs 16, 18 are arranged so that the arm 12 reaches top dead centre first and falls so that its magnet 24 operates a sealed magnetic contact unit 40 for a time dependent upon the delay produced by engagement of the arm 12 during its fall by a blade spring 32. During the delay a projection 30 on an extension 28 of the arm 12 engages the weight 10 to drive it past its top dead centre position and it falls to engage the arm 12 and assist its movement past the spring 32 to the bottom dead centre position in which the arm 12 and weight 10 remain until the weight is re-engaged by the stud 16. The spring 32 may be replaced by a permanent magnet (not shown) acting on the magnet 24 to retard its movement. Alternatively the attraction between the contact device and magnet may slow the movement of the arm 12. In an alternative arrangement (Figs. 3 and 4, not shown) the arm does not carry the permanent magnet but is a magnetic member which moves between a contact device and magnet.
